DANIEL A. CARPENTER, OF NEI/V YORK, N. Y., ASSIGNOR TO UNION TYPE- NEW JERSEY.

JERSEY, A CORPORATION OF TYPE-WRITING MACHINE.

To all whom it may concern:

Be it known that I, DANiEL A. CARPENTER,

a citizen of the United States, and aresident l of the borough of Bronx, city of New York, in the county of New York and State of N ew York, have invented certain new and useful -Im rovements in Type-Writing Machines, of which the following is a specification.

This invention relates to improvements in stop mechanism which is operative to arrest the platen of a type-writing machine, and thus to facilitate the doing of condensed billing and other work of similar character.

The invention consists of the features of construction, combinations, and arrangements of parts, which are hereinafter described, and specified in the claims.

Serial No. 325,791..

Patented Feb. 5, 1967.

Fig. 13 is a front elevation of the stop devices of a fragment of the platen-carriage.

Although the invention is shown applied to a Monarch type-writing machina-.it is to be understood that any of the well-known type-writing machines which have rotary platens may be equipped with the invention.

The platen, platen-carriage, land line-spacing mechanism of the Monarch machine are so well known that it is obviously unnecessary to fully describe their construction and operation. the machine has on it standards 2,-to which grooved guide-rails 3 and 4 are attached byk screws 5 and 6, respectively. The platencarriage 7 comprises grooved guidesS and 9, and in the ballchannels formed by the grooves in the rails 3 and 4 and guides 8 and 9 are antifriction-balls 10 and 11, by means of which the carriage is so connected to the rails 3 and 4 as to render it movable back and forth over the top plate 1.

The laten 12 is fast on the laten-shaft 13,

which as bearings in the en( s of the platen frame or carriage, and'on thefends of the shaft are finger-wheels 14 and 15. The lines acing wheel 16 is formed as part of the left` p aten-head, which is attached to the left end of the platen by screwsl 1,7. On the left end of the platen-frame is mounte the line-space ing arm 18, which is operatively connected with the pawl 19 by the arm 20, the pawl being pivoted to the usual spring-restored arm 20a. The line-spacing arm is operative to move the pawl into engagementwith the teeth of the line-spacing wheel 16 and to turn the platen for half-spacing, full-spacing, or dou-' ble-spacing. A spring and roller-detnt21 is arranged to engage the teeth ofA the linespacing wheel, the spring of this device being fastened by a screw 22 to the platen-frame. On the ends of the platen-frame are formed upright supports 23 and 24, and to these supports a rod 25 is attached, On which paperlingers are usuall)7 mounted.

The sto mechanism is applied to the platen-sha t and to the support 2 3 close to the right end of the platen-frame. The parts thereof which are mounted on the platenshaft are thev devices shown in Figs. 4 and 5 the two other devices shown in Figs. 6 and 7, and two springs. The stop device shown in The top plate 1 of the frame of.

IOO

Figs. 4 and 5 is composedof a hub 26 and a disk 27 having on it a tongue or stop 28, the disk and hub being formed together and the hub having in it a hole 29, which extends through it from end to end and in which the platen-shaft fits snugly` The parts 30 and 31 of the hub 26 are cylindrical, and next to these parts slots 32 and 33 are cut in the hub, the iiat bottom walls 33*it of the slots (see Fig. 4)' being parallel. rlhe notched and toothed disk 34, which has in it a central round hole 35, iits on the part 30 of the hub 26 and close to the left face of the disk 27. The disk 34 has cut in it and formed onit as many notches 36 and teeth 37 as there are teeth in the linespacing wheel, and on the tight face of this notched and toothed disk is a stop 38, which is fast on the disk, this stop consisting,'pref erably, of a shouldered pin, whose stem extends through a hole in the disk and is headed on the left face of the disk. The relations of the tongue or Istop 28 on the disk 27 and the stop 38 on the disk 34 are such that when the parts are put together the stop. 38 will be brought into contact with the tongue 28 if the disk 34 is turned far enough on the hub 26 in either direction. The stop 38 projects from the right face of the disk34 a distance which is slightly less than the thickness of the disk 27 The other-notched and toothed disk 39 has in it a central hole 40, in which the part 31l of the hub 26 fits loosely, and this disk is mounted on the hub 26 at the right of the disk 27, :fitting on the part 31 of the hub and against the right face of the disk 27. This disk 39 has teeth 41 and notches 42 equal in number to those of the disk 34, and on the left face of the disk 39 is a stop 43, which is fast on the disk, the stop being referably riveted to the disk, as shown. T e sto 43 is at the same distance from the axis o the hub 26 as is the stop 38 on the disk 34, so that as the disk 39 is turned on the hub 26 the stop 43 may be brought into contact withl the tongue 28on the disk 27 The bottoms of the notches 36 in the disk 34 and of the notches 42 in the disk 39 are all equally distant from the axis of the hub 26; but the teeth of the disk 34 are about twice as long as the teeth ofthe disk 39, the disk 34 being consequently somewhat' larger than the disk 39. Springs 44 and 45 are mounted on the hub 26 at the left of the disk 37 and at the right of the disk 39, respectively. These springs, which are alike, have the form shown in Figs. 1, 2, and 3 of the drawings, each consisting of a central portion 46, having on it three projections 47 and havin init an o ening similar in Yshape to a keyho e-slot. ach of these springs may be pushed over the hub, the end of the vhub passing through the round part 48 of the hole in the s ring, and then the spring may be moved e gewise, so that the ed 'es of the straight part .49 of the opening sha l. enter the slots 32 or 33 in the 'to the right end ofthe laten-frame.

hub and coperate with the parallel bottom i walls 33.a of the slots to lock the springs to turn with the hub. The spring 44 bears against the left sides of the slots 32, the parts 47 of this spring pressing against the left face of the disk 34, and the spring 45 bears against the right sides ofthe slots 33, and the parts 37 of this spring bear a ainst the right face of the disk 39. The hu 26 and disk 27 with the disks 34 and 39 and springs 44 and 45, mounted on the hub, as described, may be pushed on the platen-shaft to the position shown, the left end of the hub 26 being c'llole e hub 26 is aiiixed to the p aten-shaft by a -pin 48, driven through a hole 49 in the hub and into the platen-shaft.

A lever 50 is pivoted by a shouldered screw 51 to the right end of the rod 25 or to the support 23, one arm of this lever extending backward and downward from its fulcrum and the other extending forward therefrom in front of the rigid nger-piece 52 of the platen-frame. The rear arm 53 of this lever has on it a iange vor lip 54, which ts in the notches 36 and 42 of the-disks 34 and 39, and at the front end of this lever a finger-piece 55 is formed on it. This lever also has formed on it near its front end projections' 56 and 57, Whic'h comprise lugs 58 and 59, extending toward the part 52 of the platen-frame from the left face of the lever. A bushing 60 is fixed in the part 52 of thel platen-frame, and in this bushing, which extends close to the left face of the lever 50, 'are a coil-spring 61 and a pin 62, the outer end of this pin being pointed and the spring tending to force the, pin outward. Recesses 63, 64, and are made in the left face of the lever 50 and projections 56 and 57, these recesses being so arranged that the pointed end of the pin 62 will be forced into them as the front end of the lever is moved up and down. and will tend to keep the lever in any one of three diii'erent positions. When the front end of the lever is in its highest position, the lug 59 then being in contact with the lbushin 60, the pin 62 extends into the recess 65 an `the part 54 of the lever ex- IOO IIO,

tends into one of the notches 36 of the disk 34 andone of the notches 42 of the disk 39 as appears in Fig.' 2. When the` lug 58 is in contact with the bushing 60, the front end 4of tends into the recess 64, then the lip 54 of the lever engages the disk or rack 34, butdoes not engage the other disk or rack 39, the

.front edge of the lip 34 then being farther from the axis of the platen-shaft than are the outer ends of the teeth 41 of the last-mentioned disk. j

The stop mechanism described is so'conby the rotation, and the platen may be ro- Vwritten on it at the desired place.

tated in either direction to any extent without being arrested by the stop devices. The

springs 44 and 45 so act on the disks 34 and` 39 as to cause lthese disks to normally turn with the hub 26 and disk 27. When, however, the disks 34 and 39 are locked'by the lever or detent 50,`th,e platen, with the hub 26 and disk 27 and its stop 28, may be turned in either direction until the platen is arrested by the contact of the stop 28 with either the stop 38 or the stop 43, the pressure exerted by the sprin s 44 and 45 on the disks 34 and 39 being suc as to allow the hub 26 and disk 27 to be freely turned back and forth within thel limits indicated while the disks 34 and 39 are locked. So long as the lever 50 is disenga ed from the disksy 34`and 39 the platen may e turned in either direction to any extent by each of the finger-wheels and by the ordinary line-spacing mechanism.

To set the stops for use incondensed billing, supposing, for example, the stop 43 is not in contact with either of the' other stops 28 and 38, the handle of the lever 50 is so moved that the pin 62 enters the recess 64 in the lever and the disk 34, but noty the disk 39, is

locked by the lever Then the platen is turned forward or a line-spacing direction by the iinger-wheelfuntil it is arrested, whereu on it is turned backward bythe finger-w ieel until it is again arrested, and then a bill is fed `into the machine until its position is seen to be such as to enable 'the first line to be With the bill a sheet-of carbon and record-sheet may also be fed into the machine, the bill-sheet being given the desired lead in the usual manner to bring the first entry on the recordsheet near the top thereof. yBy the forward movement of the stop 28 with the platen before the bill has been inserted inthe machine this stop is brought into contact with the stopy 43, and thereafter the stops 43 and 28 j travel together until the stop 43 makesA contact with the stop 38. The stop y38 revents the further forward movement of t e stops 28 and 43 and of the platen, because the disk 34 is locked by the lever` or-detent 50. As 'the platen is next turned backward, the stop 43 travels with the stop 28 until tn'e latter stop makes contact with .the locked stop 38, and thebackward movement .of the platen is thus arrested.. The stop 28 is then vbetween and in contact with the stops 38 and. 43. Now the platen may b e turned forward, but not backward. As the bill, carbon,

.and record sheets are fed together into the machine the stop 43 is pushed from thev stop 38 by the stop 28, the angular movement of the stop 28 being the 'same as that of the platen and that which is required when any similar` bill is inserted inthe machine and fed to the proper position tov receive the Erst line of writing. rlhe arrangement of the three stops 28, 38, and 43 is then such that entries may be made on the bill which has been fed into the machine, and no further setting of the stops will be required sQ. lOng as the use of other bills like that in the machine continues. After the first bill has been posi` tioned in the manner described to'receive the first line of writing the lever or detent 50 is to be disengaged from the disk 34 before the bill is fed farther into the machine. As the bill, carbon7 and record sheets are fed forsheet, the line-spacingv handle 18 is actuated to give the laten a double-line-space movement in or er-to provide a proper space on the record-sheet between the last line of the last written bill and the first line of the next succeeding bill to be reproduced on the record-sheet. The handle 55 of the lever 50 is then raised until its upward movement is arrested by the. action of the lug 59 on the bushing 6() and the pin 62 engagesrwith the recess 65 inthe lever. The li or flange 54 on. the lever has then been pus ed into notches in the disks 34 and 39 and both of these disks have been locked by the lever, so as to prevent them frombeing turned. -The platen is then turned backward by one of the finger-wheels, the stop 28 leaving `the stop 43, until the platen is arrested by the action of the stop 28 on the stop 38. The next bill is then insertedin the machine and the platen is turned forward until it is again arrested, when the stop 28 reaches the stop 43. With this forward movement of the platen the new bill is fedinto the machinev IOO IIO

second bill will lbe reproduced on the recordsheet a double-line-space distance away from the last entry` on the Irecord-sheet.l The operation described may obviously be repeated indefinitely, and as the bills are successively written they Will be successively fed out ofthe machine or to a position WhereA they can be readily removed from the machine without disturbing the other sheets.

The disks 27, 34, and 39, together With the stops 28, 38, and 43 and the springs 44 and 45, are vshown in Fie. 8, inclosed in a case, which is composed ci parts 66 and 67. The part 66 of this case iits on the hub or boss 68 of the platen-frame and has attached to it an ear 69, through which the screw 51 passes, so that the case is kept in its proper position. The parts 66 and 67 of this case tit together as do a box and its cover. A slot 70 is cut in the case, as appears by Fig. 9, the lip 54 on the lever 50 extending into this slot and being movable therein into engagement with the teeth of the disks 34 and 39 within the case. This case not only protects the parts of the stop mechanism which are inclcsed therein from dust, but ,it also renders them inaccessible to the hand unless the case is opened, and thus tends to prevent them from being accidentally disarranged.

If from the stop mechanism described the disk 39 and spring 45 should be oneitted, an operative and useful structure, such as is shown in Figs. 10 and 11, would renain. The mechanism shown in these figures, however, will ordinarily be used only to linit the backward moventent of the platen. This mechanism comprises a hub 26, on .which is formed a disk'27, a stop 28, and a cylindrical surface 30, and in which are cut slots 32, the diskv27 and stop 28 being substantially the same as the disk and stop 27 and 28 and the hub 26 being substantially the same as the hub 26, except that the part of the hub 26on the right of the disk 27 is shorter than the part of the hub 26 on the right of the disk 27 and is not slotted. On the cylindrical part 30 of the hub 26, next to the left face oi' the disk 27, is mounted a disk 34, having notches 36 and teeth 37 and having a sto 38 aflixed to it. This disk is like the dis 34, except that the teeth 37 are shorter than the teeth 37. A spring 44, which is exactly like the spring 44, is mounted on the hub 26 and acts on the disk 34 as the spring 44 acts on the disk 34. The hub 26 is mounted on the platen-shaft 13 at the right of the platen-frame 7 and is fastened to the shaft by a pin 48a. A lever 50 is pivoted by a screw 51 to the upright support 23, formed on the platen-frame,or to the rod 25, this lever having an arm 53, on which is a lip or ilange 54, which iits the notches 36 and having a handle 55 On this lever' is a projection 57 and lugs 58 and 59, the latter lug being formed on the projection 57, and these lugs extend from the left face of the lever tabove and below a bushing which fixed in the part 52 ot the platen-frame and contains a spring and pin adapted to enter recesses 64 and 65 in the left face of the `lever and projection 57. The bushing 60' and -the spring and pin contained therein are the `When the disk 34 is locked with the lever 50,

the front end of the lever is in its highest position, the lug 59 being in contact with the bushing 6U. The stops 28 and 38a be ing in contact with each other, as they are shown in Fig. 10, and the disk 34 being locked by the lever 50, a bill with carbon and record sheets nlay be fed into the machine, and the operator npayeasily determine, by looking at the hill when it reaches such a position as to enable the first line to be Written on itat the desired place, it being understood that the mechanism is preferably, though not necessarily, entbodied in a. H-visible-writing? machine. The front end of the lever 50 is then depressed until the lug 58 meets the bushing 60 and the pin in the bushing enters the recess 64, so thatthe disk 34 is released, and entries are thereafter nlade on the bill which nay be fed forward in the machine any desired number of linespaces, the disk 34 traveling with the disk 27a whenever the platen is turned and the stops 28 and 38 renaining at the proper distance from each other. When. the last entry has been nade on the bill and a doubleline space is given the platen to space between copies of the different bills on the record-sheet, the disk 34 is locked and ythe platen is turned backward until it is arrested y the stops 28 and 38. Then another bill is fed into the machine until the operator observes that it is in the proper position, the handle 58 is raised, and the items of the account are written.

A inodiiication of the structure shown in Figs. 10 and 11 is illustrated in Figs. 12 and 13. This modification comprises a hub 26, disk 27, and a stop 28, precisely the same as the hub, disk, and stop 26, 27, and 28, respectively, this hub 26 being fast on the platen-shalt 13. A disk 34, having a stop 38 fast thereon, is mounted to turn on the hub 26 at the left of the disk 27, and on the hub is a spring 44, which bears against the left face ol" the disk 34 and acts 011 this disk as the spring 44 acts on the disk 34. 'l'he edge of the disk 34 is smoothinstead oibeing provided `with notches and teeth but in other respects this disk with the stop 38 thereon is essentially the same as the disk 34 with the stop 38 atlixcd to it. On the part 52 of the` platen-frame is a clamp which is composed of a base 71, jaws 72, and a thumb- IOO IOSv

screw 73. The base of the-clamp is fastened to the platen-frame by screws 74, and the jaws 72 are hingedA to the base of the clamp. The disk 34b extends between the jaws 72 of the clamp, and the thumb-screw 73 passes through and is loose in the right' jaw 72 and en ages with the left jaw'7 2, Whichcontains a t eaded hole likethat of a nut. It will be seen that the disk 34a may be locked or unlocked bymeans of this clamp, so as to render the stop 38b coperativewith the stop 28h in the same way as the stopsin thestructure shown in Figs. 10 and 11 cooperate. 'ihe elect of this clamp acting on the disk 34" is essentially the same as that of the lever a acting on the disk 34a. The operation of the yparticular form of stop mechanismshown in igs. 12 and 13 will be understood, it is believed, Without a full description thereof, inasmuch as it is essentially the same as that of the other form of mechanism shown in Figs. 10 and 11 and fully described above.

Should it be desired to limit the backward movement only of the platen when the construction of the stop mechanism is that shown in Figs. 1, 2, and 3, the portion of this mechanism which is represented by the structure shown in Figs. 1() and l 1 may beloperated to produce that result. The lever 50 would then be moved into andout of engagement with the disk 34,- bnt would notbe made to engage the disk 39. Consequently thestop 43 on the latter device would not perform its natural function, for it would move whenever the platen was turned, andv only the stop 38 would coact with the stop 28 in arresting the platen. The action of the stops 28 and 38 would be the same as that of the stops 28aL and 38a, whichwas above described.

The invention may be embodied in other forms diering in details of construction or arrangementl of parts from any of the three forms shown and specifically described herein.
